If you're looking to be right in Sukhumvit, you won't fit a better place to stay. It is close to absolutely everything and even in walking distance to the infamous "Soi Cowboy". If Sukhumvit isn't quite your scene (it's not ours) the location is still ideal for experiencing Bangkok. It's super close to transit which can take you everywhere, and a cab ride to the airport or to any of the tourist attractions won't cost much at all.
Max's property is super close to a bunch of local mini-marts and 7-11s and after three weeks of touring the islands it was awesome to be able to pick up some soap and do a load of laundry!
Although we didn't have time to experience it, the pool looked lovely, as did the gym. The only downside of the whole stay is that the bed is hard and uncomfortable, so if you have back problems this may be a bit of a pain. The place is super clean though so that counts for a lot. The biggest plusses - a handy map, lots of towels, a microwave and a toaster.
Most importantly, security in the building is really good so if you're looking for somewhere safe to stay I'd definitely recommend this spot. I would happily stay here again.
